Steve Lash reports that more lawsuits have piled on in the Facebook tracking matter:

Two renowned Baltimore plaintiffs’ attorneys have filed a class-action lawsuit against Facebook Inc., claiming that the world’s most popular social networking website has violated federal and California laws designed to protect the privacy of consumers.

William H. “Billy” Murphy Jr. and Peter G. Angelos allege Facebook has surreptitiously used online tracking technology, or “cookies,” to keep tabs on its registered users’ activities, even when they have logged off of the website. Using this technology, Facebook has been able to see what other websites its members visit, Murphy and Angelos claim in the lawsuit filed in the U.S. District Court in Northern California at San Jose.
